Permanently delete an event type. This cannot be undone.
AI agents call delete_event_type to permanently remove resources in NeuronSearchLab — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool irreversibly removes data (an event type) from the system with no recovery mechanism. While the blast radius depends on how many systems or workflows depend on that event type, permanent deletion of configuration/schema objects typically warrants high severity.
From the tool's definition Tool description explicitly states 'Permanently delete an event type. This cannot be undone.' The keywords 'Permanently delete' and 'cannot be undone' are unambiguous markers of destructive action.
Attacks that exploit this kind of access
Permanently delete an event type. This cannot be undone. It is categorised as a Destructive tool in the NeuronSearchLab MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the NeuronSearchLab MCP server in PolicyLayer and add a rule for delete_event_type: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches NeuronSearchLab. Nothing to install.
delete_event_type is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the delete_event_type rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for delete_event_type. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
delete_event_type is provided by the NeuronSearchLab MCP server (neuronsearchlab/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
delete_event_type is one line of NeuronSearchLab's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
